5 Claims. (Cl. 179-1001) This invention relates to records and to method of making the same and more particularly to records for controlling and sensory systems.

The invention is illustrated as adapted to sys- 5 tems in which a record for the reproduction of a sensory effect carries thereon a blocking component to regulate the operation of a device or series of devices.

One object of the invention is to provide 9. record for a controlling and sensory system in which there is little possibility of confusion between the sensory and blocking components.

Another object of the invention is to provide a'record for a controlling and sensory system in which the device blocking component adapted to cause actuation of controlled devices in response to its temporary interruption.

Other objects advantages and novel features of the invention will become apparent from the following description of the illustrative embodiment shown in the accompanying drawing, in which;

Figure 1 is an enlarged diagrammatic representation of the operating frequency component 25 of the record;

Figure 2 is an enlarged diagrammatic representation of the sensory component;

Figure 3 is an enlarged diagrammatic representation of the resultant sensory track; 30 Figure 4 is a diagrammatic representation of one method of producing the record; and Figure 5 is a diagrammatic representation of a system in which the record is employed.

The invention is illustrated as embodying a 35 disc record I having recorded thereon some sound or other sensor-y effect which it is desired to reproduce and a blocking component I2 superimposed thereon.

As shown in Fig. 3 the record I0 consists of a 40 single recorded track incorporating both a normal sound recording I4 (Fig. 2) which shall be called the sound track, and a device-operating recording I2 (Fig. 1), which shall be called the blocking component; that is to say the normal 45 sound track I4 is combined with the blocking component I2, so that record I0 consists mainly of recorded vibrations I3 (Fig. 3) comprising the resultant of the sound track It and the blockingcomponent I2. 50 According to the present invention, the blocking; component consists of a low frequency sound oscillation present at every portion of the sound track except at that portion in which it is desired to operate or start to operate a device or 55 series of devices.

It can readily be seen that there is very little possibility of the normal sound track having an oscillation of exactly the same frequency and in exactly the same phase relationship as that of the blocking component at the portion of the sound track in which the blocking component is absent. This insures that the device to be operated will be operated only at the proper time.

The record l0, may be prepared in any suitable manner! One desirable method being illustrated in Fig. 4 and including a suitable recorder I00, a device such as microphone I01 for delivering to the recorder through an amplifier I03 the normal sound vibrations such as the speech, music or other sound it is desired to reproduce, and a device for delivering to the recorder the blocking frequency. The device for delivering the blocking frequency is shown as an oscillator I04 and leads I06 having a normally closed switch I08. The leads I06 connect the oscillator to the recorder so that the recorder can deliver to the record the blocking component as long as the switch I00 remains closed. This switch may be opened at the time during the recording of the normal sound track at which it is desired to operate the device 32.

The recorder I00 cuts the sound track on the record I0 as the record on turntable H0 is turned preferably at substantially constant speed by motor I I2 through suitable gear means IN. 80

It is to be understood that the record i0 may be of any suitable type known in the art, that is, it may be a groove formed in a cylinder or disc, as shown, a photographic record on a film, or a magnetic record on wire.

The system (Fig. 5) in which the record is to be employed is generally similar to .that described and claimed in Patent No. 2,116,314, granted May 3, 1938, and the copending applcation of John E. Jenkins and Samuel E. Adair, Ser. No. 200,652, filed April '7, 1938. 1

An electrical pickup It may be employed to convert the mechanical vibrations on the record to electrical oscillations which may be amplified by an amplifier I8 and reproduced through a loudspeaker 20. A filter 22 may, if desired, be employed in this circuit to filter out the operating component so that it will not be reproduced by the loudspeaker.

A device operating circuit, in parallel with the above circuit may consist of a filter-24 connected to the pickup I0. The filter 24 is so designed as to permit only those oscillations to pass which correspond in frequency to that of the device operating component.

The filter 24 may be connected to an amplifler 28 which in turn delivers the amplified operating current to the relay 30. Whether the amplifier 28 is necessaryv or not depends upon the sensitivity of the relay.

The filter 24 need not be employed if the relay 30 is of the tuned type.

The relay 30 is shown normally biased by spring 3| in switch closed position, but the blocking component being present at all times toenergize relay 30 except when it is desired to close the relay switch, the switch is held open until that particular time at which the blocking component is absent on the record.

The absence of the device operating component actuates the relay. This closes circuit 32 which may be employed to operate a device or series of devices.

While only one illustrative embodiment has been shown and described it is not intended that the scope of the invention be limited to the form shown nor otherwise than by the terms of the appended claims.

What is claimed is:

1. In a controlling and. sensory system, a ree ord comprising a composite sensory component and blocking component, said blocking component comprising a predetermined frequency added to said sensory component and being interrupted at spaced intervals, and means included in said system for inaugurating a control function upon interruption of said blocking component.

2. In a controlling and sensory system, a record comprising a. composite sensory component and blocking component, said blocking component comprising a predetermined frequency added to said sensory component and being inter-' rupted at spaced intervals, and control means in said system normally restrained from operation during the reproduction of said'blocking component.

3. In a controlling and sensory system, a record containing a sensory component, a blocking component contained on such record, said blocking component being interrupted at spaced intervals, and means included in said system for inaugurating a control function upon interruption of said blockingcomponent.

4. In a controlling and sensory system, a record containing a sensory component, a blocking component on said record comprising a frequency less than cycles per second, said blocking component being interrupted at spaced intervals, and means included in said system for inaugurating a control function upon interruption of said blocking component.

5. In a controlling and sensory system, a. record containing a sensory component, a blocking component contained on said record, said blocking component being interrupted at spaced intervals, means for reproducing said sensory component and said blocking component, means for segregating said reproduced components, and

means responsive to said segregated blocking component for restraining the inception of a control function.
